Abstract
An electric wire connection body includes a first electric wire, a second electric wire electrically connected to the first electric wire, a connection portion connecting the first electric wire and the second electric wire, and an insulation coating body covering a periphery of the connection portion. The connection portion is formed by butt welding of the first electric wire and the second electric wire.
Claims13
An electric wire connection body, comprising:
- a first electric wire;
- a second electric wire electrically connected to the first electric wire;
- a connection portion connecting the first electric wire and the second electric wire;
- and
- an insulation coating body covering a periphery of the connection portion, wherein
- the connection portion is connected by butt welding of the first electric wire and the second electric wire.
A method of manufacturing an electric wire connection body in which a first electric wire and a second electric wire are connected by butt welding, the method comprising:
- an abutting step of abutting a front end surface of the first electric wire and a front end surface of the second electric wire on each other;
- and
- an irradiation step of irradiating the first electric wire and the second electric wire abutted on each other, with laser to form a connection portion by welding, wherein
- at least before the irradiation step, a region where the connection portion is to be formed is covered with an insulation coating body.
